Question

Which answer expression the polynomial in standard form?
12x^3+5+5x^2-6x^2-3x^3-9-x
A. 9x^3-x^2-x-4
B.9x^3+x^2-x-2
C. 9x^3-x^2-x+45
D.9x^5-x^2-x-4

Answer 1

x6 + 4x3 + 3x2 - 7

Answer 2

x^6 + 4x^3 + 3x^2 - 7

Can you explain why this one is in standard form?

Answer 3

Since my computer is going to die I will tell you why.

Answer 4

The highest degree is 6, so that goes first, then 3, 2 and then the constant last

Answer 5

So which one matches that format?

Answer 7

please reply

Answer 8

@Annie96
Can you check the instructions for the question to see if you are expected to give one choice or many?

Answer 9

Maybe they are looking for the one that isn't in standard form?

Answer 10

But they are all in standard form which doesn't make sense because they are looking for one.

Answer 11

@Annie96 please check the answers and make sure that there aren't any more exponents that are missing

Answer 12

d

Answer 13

Wait how did you get your answer?

Answer 14

Because the question doesn't make sense

Answer 15

oh sorry i forgot to put the problem. 12x^3+5+5x^2-6x^2-3x^3-9-x

Answer 16

@jchick oh sorry i forgot to put the problem. 12x^3+5+5x^2-6x^2-3x^3-9-x

Answer 17

Ok that makes more sense now

Answer 18

Let me check your answer

Answer 19

Is this what you got?

Answer 20

Oops wait I typed that wrong

Answer 21

yes

Answer 22

9x^3−x^2−x−4

Answer 23

Sorry just mistyped it.

Answer 24

So now is that what you had?

Answer 25

@jchick was that right

Answer 26

@annie96

This is how you should have worked it out:

12x^3+5+5x^2-6x^2-3x^3-9-x
=(12x^3-3x^3) +(5x^2-6x^2) -x +(5-9)
= ?

Answer 27

Did you simplify it @Annie96
